Thank you, everyone!
Jenn, Yes, it's tough to find an outfit for a whole day with that kind of a temperate range! Since I was just going out for a little bit, this worked. And after that, I removed the jacket and was fine.
Joy, you've got me thinking about how to take this tank further into cool weather. I don't think I'd like to need this jacket all day; it's stiff enough I don't think I'd be comfortable in it all day long, but much cooler and I might not be comfortable taking it off, without sleeves. But maybe ... I've seen a few looks lately of layering that I might be able to pull off, wearing something underneath this tank. Oh, and I don't own booties, but I do own boots, at this point.
LavenderMoon, if I can figure out how to get some sleeves added, a scarf might at some point get added as it really gets cooler. But I would have been sad to cover up the asymmetrical neckline of the top with a scarf. I don't have any wedges, but I've been contemplating some platform shoes ...
Brooklyn, I'm sure jewelry would work, but I'm not much of a jewelry person, apparently. I've always got my wedding ring, and specs, and sometimes I add earrings (which would have worked here, if I had appropriate ones). I just didn't think of it yesterday.
JAileen, It's certainly not normal here either, yet! Even when we have cooler summers, it's usually blazing hot for the state fair, so we'll see what next week brings.
